Early-Development ZNF804A Linked to Hyper-Excitable Neurons in Schizophrenia
TL;DR Summary
A precision functional genomics study shows the schizophrenia risk gene ZNF804A is most active in glutamatergic neurons during the second trimester. Using CRISPR-Cas9 to suppress ZNF804A in developing neurons increased local protein translation at dendritic tips, raised synapse density, and heightened electrical excitability, linking this genetic risk factor to a specific neurodevelopmental mechanism that may contribute to schizophrenia.
